RGLLING-lVIlLL GUIDE.

SPECIFICATION forming part of Letters Patent No. 385,434, dated July 3, 1888.

Application tiled November 1S, i887. Serial No. 255,534. (No model.)

.To @ZZ whom, t may concern.-

one side, movable longitudinallyon the crane- Be itknown that I, JOHN W. NVALsH, a resibar, and secured thereon by means of the plate dent of the city of Troy, in the county ofRensselaer and Slate of New York, have invented certain new and useful Improvements in Rolling-Mill Guides; andI do hereby declare that the following is a full, clear, and exact description of the invention, that will enable others skilled in the art to which it appertains m to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Similar letters refer to similar parts in the I5 several figures therein.

My invention relates to improvements in rolling-mill guides; and it consists ofthe novel construction and combination of parts hereinafter described,and pointed out in the claims.

The objects of theinvention are pointed out in connection with the following description of my preferred mechanism, in which Figure l ofthe drawings is afront elevation of a portion of a rail-rolling mill showing my 2 improved device in position to guide the rails.

Fig. 2 is a side view of my improved device,

the relative position of the rolls being indicated by the broken curved lines. Fig. 3 is a top plan view of the parts shown in Fig. 2. Fig. 4 is a cross-sectional view of one of the sides of the guides, taken at broken line Y Y in Fig. 3. Fig. 5 is a view similar to thatshown in Fig. 4, taken at the broken line X X in Fig. 3.

A A are the housings,and R RiBa are respectively the upper, middle, and lower rolls of a three-high mill. The crane-bars B B', supported at each end by the housings, support the guides which form the subject of my ine 4o vention, and serve to guide the rails, plates,

bars, or other' product of the finishing-rolls of a rolling-mill on their way to and from the passes P between the rolls.

As heretofore constructed, the sides forming '45 the guides have been separately bolted to their supporting-bar,oalled cranebar, and whenever it was desired to change the guides from one pass tosanother much time was necessa rily consumed in loosening, adjusting, and se- 5o curing the guides upon the crane-bar.

I makeuse ofasleeve, S,preferably opened on S', covering the open side and secured to the ears Si, projecting from the sleeve, by means of screws or rivets Sl.

The sides C of the guide are provided on their lower side with the guidelugs C, located to receive the sleeve between them, as shown in Fig. 2, and with apertures passing down 6o through the lugs adapted to receive the bolts a, by means of which and the clip a. and nuts a2 the sides are firmly secured to the movable sleeve. The sleeve is provided with one or more setscrews, b, adapted to tit'and travel 65 longitudinally of the slot b in the bar when the sleeve vis moved, and to hold the sleeve in any desired position upon the bar.

To change the sides from one pass to another, it is only necessary to loosen the set- 7o screws, slide the sleeve to the desired position, and tighten the screws. As the adjustment of the two sides relatively to each other :and angularly to the crane-bar is not disturbed, very little time or skill is required to properly make the change. I also provide a detachable faceplate, G and C2, for the sides, which can be slid to and from the pass, and quickly withdrawn and another substituted in its place, when desired. The plate and sides have a 8o dovetail tongue and groove,d, (shown in Figs.

4 and 5,) which secures them together,and the plate is prevented from sliding when adjusted upon the side by means of a key, K, adapted to be inserted in aslot in the tongue when registering with a similar slot in the flanges forming the groove.

I have shown the face plate C longer than the plate C, which adapts the guide to atrain of rolls having passes for railway-rails, and 9o grooves and collars on the rolls, substantially as shown iurFig. l, wherein the collar D adA jacent to the pass is smaller in diameter than the collar D', which requires the faceplate on that side of the pass to project farther in between the rolls, as indicated partly by dotted lines in Fig. 2.

In transferring guides whose sides have the face-plate adjustable, as I have described, from one pass to another past a projecting collar 10o it is only necessary to withdraw the key and slide the plate back 'flush with the side, whereupon both can be easily moved with the sleeve past the proj eeting collar Dto the desired pass.

It sometimes happens that the rails are twisted or bent a little as they emerge from the passes, and it was customary heretofore to loosen up the sides, one 0r both, and put wedges or props under one edge to cause them to incline in the proper direction to true np the rail.

I ain able to easily and quickly provide for such emergencies by having face-plates of different forms, whereby one of the proper form to accomplish the desired result can be quickly and securely substituted.

I have indicated by dotted lines in Fig. 4 a plate beveled so as to be thinner on the lower edge, and in Fig. 5 so as to be thinner ou the upper edge.

By substituting the proper plate the rail eau be diverted to the proper course.

By having the face-plate detachable I am able tosubstitute thicker or thinuerl'aee-plates, thus aecommodatingthe guide to passes ol' different widths without distnrbing the adjust ment of the sides upon their su pporting-sleeve.

One of the sides may have a flange, E, projeeting laterally over the course ofthe rail, as shown by dotted lines in Fig. 1, to preventthe rails from leaving the guide.

That I claim as new, and desire to secure by Letters Patent, is*

l. A guide for rolling-mills, consisting of two sides bolted to a common sleeve adjustable longitudinally upon the crane-bar, substantiallyas described, and for the purposes set forth. Y

2. In a guide for rolling-mills, the combination, with a side plate, of a face-plate secured to the side plate and ad j nstable longitudi nally thereon, substantially as described, and for the purposes set forth. n

3. In a guide for rolling-mills, the combi nation, with a side plate, of a face-plate connected therewith by tongue and groove extending longitndinally ot' the plates, and akey fitting a vertical slot in said tongue and groove, substantially as described, and for the purposes set forth.

4. In a guide for rolling-mills, the combination, with a side plate, ofa detachable face plate beveled to present an inclined face, substantially as described, and for the purposes set forth,

In testimony whereof I have hereunto set my hand this 14th day of November, 1887.
